Claims (5)
- 環状内側バンド(30)と環状外側バンド(32)との間に配置された固定タービンベーン(28)のアレイを備えたタービンノズル(26)であって、前記ベーン(28)の各々が、凹状正圧側面と、対向する前縁及び後縁間で翼弦方向に延びる横方向に対向する凸状負圧側面とを含み、前記ベーン(28)が、前記内側バンド(30)、前記外側バンド(32)、及び隣接する第1及び第2のベーン(28)間に各々が境界付けられる複数の流路を間に定めるように配列され、前記流路の各々における前記内側バンド(30)の表面が、前縁に隣接する前記第1のベーン(28)の正圧側面に隣接した比較的高い半径方向高さのピーク(46)と、前記前縁の後方の前記第2のベーン(28)の負圧側面に対して平行且つ離間して配置された比較的低い半径方向高さのトラフ(48)とを含む非軸対称形状で輪郭形成されており、
前記トラフ(48)の最深部分は、前記第2のベーンの負圧面側から離間し、
前記ピーク(46)及びトラフ(48)が、前記第1及び第2のベーン(28)間の前記内側バンド(30)に沿って軸方向に延びる弓形チャンネルを協働して定め、
前記ピーク(46)が、前記前縁と翼弦中間位置との間の各ベーン(28)中途の正圧側面に中心があり、そこから前方、後方、及び側方で高さが減少し、前記トラフ(48)が、前記ベーンの最大厚み付近の前記負圧側面に中心があり、そこから前方、後方、及び側方の深さが減少する、
タービンノズル(26)。 - 前記ピーク(46)が、前記第2のベーン(28)の負圧側面に沿って前記トラフに接合するため前記第1のベーン(28)の前縁付近で高さが減少し、前記トラフ(48)が、前記第2のベーン(28)の負圧側面に沿って後縁にまで延びる、
請求項1に記載のタービンノズル(26)。 - 前記トラフ(48)の最深部分を定める線が、前記第2のベーン(28)の負圧側面から第1のベーン(28)の正圧側面までの接線方向距離の約10%から約30%に位置付けられる、
請求項1又は2に記載のタービンノズル(26)。 - 前記トラフ(48)の最深部分を定める線が、前記第2のベーン(28)の負圧側面から前記第1のベーン(28)の正圧側面までの接線方向距離の約20%に位置付けられる、
請求項3に記載のタービンノズル(26)。 - 前記各ベーン(28)の後縁の後方の前記内側バンド(30)の表面には、根元における前記各ベーン(28)の後縁と前記表面との間に明瞭な交差部を定めるように実質的にあらゆるリッジが存在しない、
請求項1乃至4のいずれか1項に記載のタービンノズル(26)。
